Synthesis and Multinuclear NMR Investigation on Binuclear Gold(I)-Diphenylphosphinoammine (dppa)-Arylazoimidazole Complexes
Reaction of [Au2(dppa)Cl2] with AgOTf in dichloromethane medium followed ligand addition leads to [Au2(dppa)(RaaiR)](OTf) [RaaiR = p-R-C6H4-N=N-C3H2-NN-1-R, (1-3), abbreviated as N,N-chelator, where N(imidazole) and N(azo) represent N and N, respectively; R = H (a), Me (b), Cl (c) and R = Me (1), CH2CH3 (2), CH2Ph (3), OSO2CF3 is the triflate anion, dppa is diphenylphosphinoammine ring]. The ma...

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
Palladium(ii) Dppe Arylazoimidazole Complexes: Synthesis, and Spectroscopic Characterization
Understanding photo induced electron transfer is a major scientific objective and is of technological impor tance for the design of synthetic molecular devices [1–3]. It is clear that the ability to mimic the natural photosyn thesis process in the laboratory would have great techno logical significance in terms of solar energy conversion and storage. Synthetic porphyrin based assemblies have be...
متن کاملMultinuclear Solid-State NMR Investigation of Hexaniobate and Hexatantalate Compounds.
This work determines the potential of solid-state NMR techniques to probe proton, alkali, and niobium environments in Lindqvist salts. Na7HNb6O19·15H2O (1), K8Nb6O19·16H2O (2), and Na8Ta6O19·24.5H2O (3) have been studied by solid-state static and magic angle spinning (MAS) NMR at high and ultrahigh magnetic field (16.4 and 19.9 T). (1)H MAS NMR was found to be a convenient and straightforward t...
متن کاملSynthesis of Binuclear Copper (II) Complexes with Expanded Porphyrins
The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...
